루프 분할과 종속함수를 이용한 다중첨자 중첩루프의 종속성 제거 기법
박상일,양황규,윤성대 東西大學校 2001 동서논문집 Vol.7 No.-
In this paper, we propose a new method to parallelize multidimensional subscript loop with non-uniform distance. A loop comprise most of the computation in a program and the most important source of parallelism. Multidimensional subscript within a loop difficult to determine for distance to be required loop dependence elimination. Therefore, we propose new methods that used dependency function to eliminate dependence.
Expression Analysis of the Ligand to Ly-6E.1 Mouse Hematopoietic Stem Cell Antigen
Hwang, Dae-Youn,Min, Dul-Lei,Sonn, Chung-Hee,Chang, Mi-Ra,Lee, Mi-Hyun,Paik, Sang-Gi,Kim, Young-Sang The Korean Society for Integrative Biology 1997 Korean journal of biological sciences Vol.1 No.1
Ly-6E.1 antigen was proposed as a regulatory molecule of T lymphocyte activation, a hematopoietic stem cell marker, a memory cell marker, and an adhesion molecule. Though there were several reports suggesting the presence of Ly-6 ligand, the characterization of the ligand was not yet performed, As an attempt to screen the expression of Ly-6E.1 ligand, we prepared a probe for detecting Ly-6E.1 ligand by producing a fusion protein between Ly-6E.1 and $hlgC_{r1}$, A mammalian cell expression vector with Ly-6E.$1/hlgC_{r1}$ chimeric cDNA was transfected in SP2/0-Ag14 myeloma cells, and stable transfectants were selected. The fusion protein was produced as a dimer and maintained the epitopes for monoclonal antibodies specific for Ly-6E.1 and for anti-human lgG antibody. The purified fusion protein through Gammabind G column was used for FACS analyses for the expression of Ly-6E.1 ligand. The fusion protein interacted with several cell lines originating from B cells, T cells, or monocytes. The fusion Protein also strongly stained bone marrow, lymph node, and spleen cells, but thymic cells weakly, if any. The staining was more obvious in C57BL/6 $(Ly-6^b)$ than Balb/c $(Ly-6^a)$ mice. These results suggest that the interaction of Ly-6E.1 with Ly-6E.1 ligand may function both in the stem cell environment and in the activation of mature lymphocytes. The fusion protein may be a valuable tool in characterization of biochemical properties of the Ly-6E.1 ligand and, further, in isolating its cDNA.
